That's great info, Dooki.
I'm caught up in the holidays, family things, etc. but I will give this a run when things get back to normal.
I appreciate the analysis.
Does it do lofting -- like in Rhino I created two offset concentric circles on same central axis and arrayed them along a curve. When I lofted them I ended up with a corregated hose (kind of like the one from your dryer's exhaust).
Anyway, ViaCad sounds like a good tool.
Happy Hollidays
